摘要

PROCESS TO REDUCE A MATERIAL CONTAINING METAL, EXTRACTIVE METALLURGICAL PROCESS FOR THE CHEMICAL REDUCTION OF A MINING OR CONCENTRATE CONTAINING IRON, AND, PRODUCT describes a process for reducing a material containing metal, the process comprising: providing a material containing metal (5), heat said material containing metal by convection and / or conduction and / or radiation devices (2), expose said material containing metal to microwave energy (3), expose said material containing metal to radio frequency energy (RF) and expose said metal-containing material to a reducing agent (8). The method, which does not involve dielectric heating during exposure to MW and RF energy, allows for more efficient chemical reduction in terms of ores and ore concentrates containing metals and increases metallization yield.
